9.3.3. Booster Commissioning
z Downlink gain setting
First the alarm LED only indicates the downlink input power level, here we use color of Alarm LED
to adjust the gain of the Booster. Alarm LED color must remain green. As for the downlink working
performance, it is a good working point that Alarm LED maintains “Green” color with the intention of turning
orange; here we refer as “edge point”. At this time, downlink output power and coverage effect are stable.
